Meta just handed Corning a $6 billion commitment through 2030 to supply fiber-optic cables for its AI data centers, CEO Wendell Weeks told CNBC in an exclusive interview. The deal marks one of the largest infrastructure partnerships in the AI buildout, with the 175-year-old glassmaker - best known for supplying iPhone screens - now expanding its North Carolina facility into what it claims will be the world's largest fiber-optic cable plant. It's a sign of how the AI race is reshaping century-old supply chains and creating unexpected winners in the infrastructure layer.
Meta is placing a massive bet on glass. The social media giant has committed to paying Corning up to $6 billion through 2030 for fiber-optic cables to wire its AI data centers, CEO Wendell Weeks revealed to CNBC during a factory tour in Hickory, North Carolina. It's a deal that transforms the 175-year-old glassmaker - once synonymous with Pyrex cookware and iPhone screens - into a critical infrastructure player in the AI race.
The partnership comes as Meta scrambles to build 30 data centers by 2028, including 26 facilities across the U.S., as part of a $600 billion domestic infrastructure commitment. Two of the company's largest projects - the one-gigawatt Prometheus site in New Albany, Ohio, and the five-gigawatt Hyperion facility in Richland Parish, Louisiana - will both run on Corning fiber under the new agreement. "We want to have a domestic supply chain that's available to support that," Joel Kaplan, Meta's chief global affairs officer, told CNBC.
But this isn't just about Meta. Corning is expanding its Hickory plant to meet surging demand from Nvidia, OpenAI, Google, Amazon, and Microsoft - all racing to build AI infrastructure at unprecedented scale. "Almost every phone call I get from my customers is trying to see, how do we get them more?" Weeks said. "I think next year the hyperscalers will be our biggest customers."
The numbers back him up. Revenue in Corning's optical communications business, which includes fiber, jumped 33% in the third quarter to $1.65 billion, while total sales rose 14% to $4.27 billion, according to the company's earnings release. Enterprise sales of optical communications soared 58% in the quarter, "driven by the continued strong adoption of Corning's new Gen AI products." Shares have climbed more than 75% over the past year, making optical communications the company's largest and fastest-growing segment.
AI data centers require fundamentally different infrastructure than traditional cloud facilities. Weeks describes it as a "whole separate network" that's "trying to create the connections just like it is between the neurons in your brain." That level of connectivity demands so much fiber that Corning invented an entirely new cable type called Contour specifically for AI workloads. The new design fits twice as many fiber strands into a standard conduit and reduces 16 connectors down to a single one - crucial for facilities like Meta's Louisiana data center, which alone will require 8 million miles of optical fiber.
Weeks' name is on the Contour patent, and he says development began more than five years ago - well before ChatGPT's 2022 debut - following a conversation with an unnamed leader in generative AI. "They were saying, 'Listen, you need to put in a lot more capacity,'" Weeks recalled. "He's like, 'No, you totally don't get it. This is what's going to happen and how much compute is going to be needed, how the scaling laws are working.'"
The physics favor fiber. Unlike copper cables that transmit data as electrical signals, fiber-optic cables send information as photons - pulses of light traveling through hair-thin glass strands at nearly the speed of light. "Moving photons is between five and 20 times lower power usage than moving electrons," Weeks explained. "As power becomes a bigger and bigger issue, fiber inevitably gets closer and closer and closer to the compute."
That shift could extend all the way into server racks. While copper cables still dominate connections between chips within individual servers, Weeks says the transition to fiber is "inevitable" once GPU counts per rack climb into the hundreds. "Fiber optics become much more economical and much more power efficient" at that scale, he said.
For Meta, the Corning deal represents a critical piece of its AI infrastructure puzzle. But the strategy has puzzled Wall Street. Meta's stock underperformed the market in 2025 and had its worst day in three years last October after announcing ambitious AI spending without a clear monetization plan. The company is betting that winning the AI race requires controlling the full infrastructure stack - from chips to cables to data centers.
Corning, meanwhile, is no stranger to boom-and-bust cycles. The company rode fiber demand to an eightfold stock increase during the dot-com era, from 1997 through its September 2000 peak, before losing over 90% of its value in the subsequent collapse. "What we learned then was that it wasn't enough to do great innovations," Weeks said.
This time, he's betting diversification provides a cushion. Beyond fiber, Corning supplies glass for Apple iPhones (including a $2.5 billion deal announced in August), TV screens, auto components, and pharmaceutical vials. "We're built to withstand bad weather," Weeks said. Meta Marshall, a Morgan Stanley analyst covering networking equipment, agrees Corning can likely manage volatility. "The market will still need TVs and phones and cars and auto glass and vials for medications," said Marshall, who has a hold rating on the stock.
The AI infrastructure boom shows no signs of slowing. The industry announced more than $1 trillion in compute deals in 2025 alone, though some experts warn of bubble dynamics. Weeks isn't worried about demand evaporating. Fiber-optic usage has grown about 7% annually on average over the long term, he notes - "so we'll find a good use for it." And he's confident in Meta's execution: "In the end, really technical excellence, willingness to commit to the infrastructure, compute matters."
Mike O'Day, Corning's head of fiber optics, told CNBC the company has now manufactured over 1.3 billion miles of optical fiber in its history. With facilities expanding across North Carolina to meet hyperscaler demand, that number is about to climb dramatically. The Hickory plant expansion will make it the largest fiber-optic cable facility in the world, according to Corning.
Both Corning and Meta report fourth-quarter earnings on Wednesday, providing fresh insight into how the AI infrastructure buildout is reshaping financial results. For Corning, it's a remarkable transformation - from Edison's light bulbs in the 1870s to cookware, spacecraft windows, and now the nervous system of AI.
The Meta-Corning deal crystallizes how the AI infrastructure race is creating unexpected winners far beyond chip makers and cloud providers. A 175-year-old glass company that survived the dot-com crash is now at the center of the AI buildout, expanding factories to meet demand from every major hyperscaler. As Meta pours $600 billion into domestic data centers and the industry places trillion-dollar compute bets, the companies wiring it all together - literally - are seeing historic growth. Whether this turns into sustainable business or another bubble remains the open question, but for now, the fiber has to get laid. Both Corning and Meta report earnings Wednesday, offering fresh data on whether Wall Street buys the infrastructure thesis or remains skeptical of AI monetization timelines.
